Coronary artery fistulas (CAFs) are rare defects in the coronary circulation system that are usually diagnosed incidentally with cardiac imaging. Although the prognosis of coronary artery fistulas is highly variable, the complications to which they predispose patients are ultimately the determining factor. The authors describe a case of a 56-year-old male, a smoker, hospitalised for worsening dyspnoea on progressively smaller efforts, in the context of acute heart failure. During hospitalisation and imaging exams, a coronary-bronchial fistula was identified.
CAFs are rare and may present with different anatomical configurations and clinical syndromes.Only 17% of CAFs reported draining into the pulmonary circulation.The optimal timing and role of CAFs intervention are not clearly defined.
冠状动脉瘘（CAF）是冠状动脉循环系统中罕见的缺陷，通常在心脏成像时偶然被诊断出来。尽管冠状动脉瘘的预后差异很大，但它们使患者易患的并发症最终是决定因素。作者描述了一例56岁男性吸烟者的病例，该患者因在急性心力衰竭的情况下，活动量逐渐减小时呼吸困难加重而住院。在住院和影像学检查期间，发现了冠状动脉支气管瘘。
冠状动脉瘘很罕见，可能呈现不同的解剖结构和临床综合征。报告的冠状动脉瘘中只有17%引流至肺循环。冠状动脉瘘干预的最佳时机和作用尚未明确界定。
